The Pynq community started a new set of tutorials: https://discuss.pynq.io/t/tutorial-pynq-dma-part-1-hardware-design/3133 .

To get the working set in your jupyter workbooks:

form /home/xilinx , execute these 3 steps:

If you want to have the Vivado project created automatically (not needed, the bit and .hwh files are provided and instructions to manually create the project are lesson part 1) , there are scripts available.

If you are on a windows pc, Start Vivado Tcl Shell 2020.1

The project will be available in a new myproj subfolder.

I've translated the Johnson Counter from Verilog to VHDL. Another VHDL implementation is available from Jon: VIDOR 4000: Johnson Counter

We're presenting this project in the PYNQ workshops next week and I can't explain Verilog code [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-8d008f8a-b104-4649-85de-d2b00e491d3c/contentimage_5F00_1.png:16:16]. Also a reset signal is added.

I've put the link to the individual sources in each post.

[mention:acaf6a9338de4eef8f6717d5561ed01d:e9ed411860ed4f2ba0265705b8793d05], thanks for explaining the full procedure of implementation. The johnson counter did work well.

I was trying to pullout those 4 IOs mapped to onboard LEDs to the PMODA to control stepper motor using the same johnson counter. I believe the synthesis remains same and rerun the implementation directly to change pin mappings over .xdc file.

[View:/resized-image/__size/1366x768/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-8d008f8a-b104-4649-85de-d2b00e491d3c/contentimage_5F00_208513.png:1366:768][View:/resized-image/__size/1366x768/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-8d008f8a-b104-4649-85de-d2b00e491d3c/contentimage_5F00_208514.png:1366:768]

I changed pinouts to PMODA's 4 IOs and overwrote the bitstream and .tcl block design file. Then copied to Jupyter notebook and ran the same script(johnson_counter as in video tutorial). I now see still the onboard LEDs blink(scroll over) even if mappings are changed. I am wondering if i missed any critical steps........ Any clues?

I installed Vivado 2020-1 now, to recreate the base and logictools designs.

First step is to generate the IP. So far so good:

Creating the project worked:

I am having trouble in installing the board in Vivado. The directory mentioned above, I have not been able to locate. Please can anyone help how to do as per the second solution mentioned above.

I've now learned how to pass GPIO , reset and clock between the embedded ARM and FPGA.

Next action: how to pass data over memory mapped registers.
